Title (EN) POWER SUPPLY CONVERTER
(FR) CONVERTISSEUR D'ALIMENTATION ÉLECTRIQUE
(ZH) 一种电源变换器
Abstract:
(EN) A power supply converter, comprising a branch a, a branch b, a second transformer (T1B), a first transistor (Q1), a second transistor (Q2) and a first transformer (T1A). The power supply converter can not only accelerate the starting of a transistor, but can also improve the conversion efficiency, enhance a capacitive load starting capability, enhance a low temperature starting capability and realize a short-circuit protection function, and can work normally at different environmental temperatures. The power supply converter has a low no-load power consumption and has a long-term short-circuit protection function.
(FR) L'invention concerne un convertisseur d'alimentation électrique, comprenant une branche a, une branche b, un second transformateur (T1B), un premier transistor (Q1), un second transistor (Q2) et un premier transformateur (T1A). Le convertisseur d'alimentation électrique peut non seulement accélérer le démarrage d'un transistor, mais peut également améliorer l'efficacité de conversion, améliorer une capacité de démarrage de charge capacitive, améliorer une capacité de démarrage à basse température et réaliser une fonction de protection contre les courts-circuits, et peut fonctionner normalement à différentes températures environnementales. Le convertisseur d'alimentation électrique a une faible consommation d'énergie sans charge et a une fonction de protection contre les courts-circuits à long terme.
(ZH) 一种电源变换器,包括支路a、支路b、第二变压器(T1B)、第一晶体管(Q1)、第二晶体管(Q2)以及第一变压器(T1A)。该电源变换器既能加速启动晶体管,又可以提高转换效率、提升带容性负载启动能力、提升低温启动能力和实现短路保护功能,可以在不同环境温度下正常工作。该电源变换器空载功耗低并具有长时间短路保护功能。
